The keto diet is a low-carb, high-fat eating plan designed to put the body into a state of ketosis, where it burns fat instead of carbohydrates for energy. While fruit is typically associated with health and nutrition, it is also high in carbohydrates and sugars, which can be detrimental to the keto diet. However, this does not mean that fruit is entirely off-limits on the keto diet. There are several fruits that are low in carbohydrates and suitable for keto, including avocados, lemons, tomatoes, berries, and kiwis. These fruits can be enjoyed in moderation as part of a balanced keto diet, ensuring that individuals receive adequate nutrition while maintaining ketosis.

What You'll Learn
Avocados, olives, and other fruits high in fat
The keto diet is a low-carb, high-fat eating plan that puts your body into a metabolic state called ketosis, where it becomes very efficient at burning fat. This diet is popular for weight loss, but it has also been used to treat epilepsy and is being studied for its potential in treating cancer.
Avocados are a keto superstar. They are low in net carbs and packed with healthy fats and essential nutrients, making them a perfect addition to a keto meal plan. A standard avocado contains 5g of monounsaturated fat, 1g of polyunsaturated fat, and 6g of healthy fats overall, with only 4g of carbohydrates. Avocados are also a good source of fibre, aiding digestion and helping to maintain steady blood sugar levels. They are incredibly versatile and can be eaten alone, in salads, soups, desserts, sauces, or the famous guacamole. You can even make avocado fries by coating avocado slices in almond flour and baking or air-frying them for a crispy, keto-friendly snack.
Olives are another excellent choice for the keto diet. Like avocados, they are higher in fat than carbs, with only around 3 net carbs per 100g of olives. They are a great source of healthy monounsaturated fat and are loaded with antioxidants, vitamins, and minerals. Olives are a perfect snack or salad topping, and olive oil is a great way to flavour your meals while staying true to the keto diet.
Other fruits that are high in fat and suitable for the keto diet include lemons, berries, and kiwis, although these should be consumed in moderation due to their higher net carb content.

Tomatoes, strawberries, and other fruits with lycopene
While on a keto diet, it is important to consume fruits that are low in carbohydrates and sugar. Fruits with lycopene, an antioxidant found in red, pink, and orange fruits and vegetables, can be a great addition to your keto diet.
Tomatoes, scientifically classified as fruits, are a major source of lycopene. They are also a considerable source of vitamins K, A, C, fibre, and carbohydrates, as well as some amounts of iron, potassium, phosphorus, and sulphur. They are also low in sodium, fat, and calories. The lycopene content in tomatoes provides various health benefits, such as reducing the risk of heart disease and improving blood vessel function. Additionally, tomatoes are low-carb and suitable for a keto diet.
Strawberries are another fruit rich in lycopene and antioxidants, including vitamin C. They also contain manganese, calcium, and folate. A 100-gram serving of strawberries contains 7.7 grams of carbs, making them a relatively low-carb option. According to a 2021 study, consuming strawberries daily may promote better blood vessel function and protect against the risk of a heart attack.
Other fruits that contain lycopene include watermelon, apricots, pink grapefruits, papayas, peaches, and cranberries. Watermelon, in particular, is a good choice for a keto diet as it is low in carbohydrates and provides hydration and essential vitamins and minerals.
In addition to fruits, lycopene can also be found in processed tomato products like tomato paste, ketchup, sauce juices, and soups. It is important to note that the keto diet restricts carbohydrate consumption to less than 50 grams per day, so the total carb count of these fruits should be considered when planning your meals.

Lemons, limes, and other citrus fruits
Lemons are keto-friendly fruits that are low in carbohydrates. They are rich in essential nutrients and phytochemicals with several health-promoting properties. Consuming lemon juice in moderation will not raise your blood sugar or impact your insulin levels, which maintains ketosis and keeps your metabolism in fat-burning mode. Lemon juice provides only around 2 grams of carbs per ounce, which is not enough to raise your blood sugar and will keep insulin levels low.
Regularly consuming lemons on keto is a great way to support healthy vitamin C and folate levels. Lemons can also lower your risk of kidney stones, promote weight loss, boost liver function, and support healthy skin. Lemons are also a great addition to keto-friendly baking and dessert recipes. They can be used to make refreshing summer thyme lemonade or lemon cream and blackberry fat bombs.
Limes are also keto-friendly. One cup of freshly squeezed lime juice contains 19 grams of carbs, while one tablespoon has 1.2 grams of carbs. As long as you do not consume too much, it will not knock you out of ketosis.
While following a keto diet, it is important to be mindful of your carbohydrate intake. The keto diet is a restrictive eating plan focused on extremely low carbohydrate consumption. People following the keto diet are instructed to limit carbohydrates to less than 50 grams per day, with some sources suggesting no more than 20 grams daily.
Other fruits that are considered keto-friendly include avocados, berries, tomatoes, and kiwis. These fruits are generally low in carbohydrates and sugars, and can be consumed in moderation while following a keto diet.

Kiwis, blueberries, and other fruits with higher net carbs
The keto diet is a low-carbohydrate, high-fat eating plan designed to put the body into a state of ketosis, where it burns fat as a primary fuel source instead of carbohydrates. This diet is often used for weight loss, diabetes prevention, and epilepsy management. While the keto diet restricts many fruits due to their high carbohydrate content, some fruits with lower net carbs can be included in moderation.
Kiwis are considered a suitable fruit for the keto diet by some sources, but they have a higher net carb content than other keto-friendly fruits. A 75-gram kiwifruit contains approximately 10.5 grams of carbohydrates and 2.25 grams of fiber, resulting in net carbs of around 8.25 grams. Due to their higher net carb content, those adhering to the keto diet may want to consume kiwis sparingly and monitor their carbohydrate intake throughout the day to maintain ketosis.
Blueberries are another fruit with a relatively high carbohydrate count. A half-cup serving of raw blueberries (72-74 grams) contains about 10.9-11 grams of total carbohydrates and 1.8 grams of fiber, yielding approximately 9.1 grams of net carbs. While blueberries can be included in a keto diet, particularly in their raw form, portion size should be considered, especially when focusing on net carbs.
Other fruits with higher net carbs that may require mindful consumption on the keto diet include starfruit and cucumbers. Starfruit provides about nine grams of carbohydrates and four grams of fiber per cup, resulting in five grams of net carbs. Cucumbers, being mostly water, have nine grams of net carbs. It is important to note that the keto diet inherently lacks fiber, so including these fruits in moderation can provide essential fiber and various nutrients while still adhering to the keto guidelines.

Cantaloupe, watermelon, and other low-carbohydrate fruits
Cantaloupe, watermelon, and other fruits can be included in a keto diet, but it is important to monitor your consumption. The keto diet is a restrictive, low-carbohydrate eating plan that limits daily carbohydrate consumption to less than 50 grams, with some sources suggesting no more than 20 grams. Cantaloupe and watermelon are low-carb fruits that can fit within these limits in moderate portions.
Cantaloupe is a nutritious option, providing vitamins A and C, folate, potassium, and beta-carotene. A half-cup of diced cantaloupe contains 6.5 grams of carbs, while a 100-gram serving has about 8 grams of carbs. Cantaloupe may be more satiating than other fruits, making it a satisfying choice.
Watermelon is also a low-carb fruit, packed with vitamins A and C, beta-carotene, and lycopene. Lycopene gives watermelon its pink colour and offers anti-inflammatory benefits, helping to fight diseases like cancer, heart disease, and diabetes. A half-cup of diced watermelon contains 5.5 grams of carbs, while a 100-gram serving provides 7.5 grams of carbs.
Other low-carb fruits that can be considered for a keto diet include avocados, berries, peaches, and kiwis. However, portion sizes should be kept in mind to stay within the strict carbohydrate limits of the keto diet. It is recommended to consult a registered dietitian or healthcare provider for guidance on portion sizes and the suitability of specific fruits within the keto diet.
